In teasing this fall’s final episodes and the second half of Season 3, Once cocreator Eddy Kitsis told TVLine that the show’s springtime arc will feature “a new villain that we are very excited about, that we may reveal at the end of Episode 11… maybe not.”

And though I thought Kitsis was being cheeky/dodgy with that timeframe for the intro, it turns out that Mader’s meanie will be revealed during a midseason promo airing after the Dec. 15 fall finale.

Still, no details on who the British headturner is playing are being divulged. But that’s what Al Gore made comments sections for. So grab your tinfoil sorcerer’s apprentice hat and speculate!
